Andrew H. Knoll.
Life on a Young Planet: the first three billion years of evolution on earth.
Princeton University Press. 2003

Australopithecines, dinosaurs, trilobites—such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.
